Years ago this Douglas fir dropped off the Kala Point cliffs during a landslide, and embedded itself in the beach. At most high tides, it gets covered by water; at most lows it get exposed to the air. The barnacles that can survive through the low tides are rewarded with fresh food when the waters return.
